Obesity linked to breast cancer
By Jimmy Downs
"Saturday Sept 29, 2012 (foodconsumer.org) -- Women who live with obesity are at higher risk for breast cancer compared with those who have a normal body mass index (BMI), according to a new study in the International Journal of Cancer.
Kami K. White at University of Hawaii Cancer Center in Honolulu, HI and colleagues conducted the study and found Native Hawaiian women who had a bodymass index 30 kg/m2 or greater or obesity were 82 percent more likely to develop breast cancer compared to those who had a BMI of 20 to 24.9 kg/m2.
.............................
When both BMI and weight gain were analysed together, adult weight gain had a more significantly positive impact on the risk of breast cancer than BMI, suggesting it is important to maintain a healthy weight throughout adulthood for the prevention of breast cancer in postmenopausal women.
Breast cancer is preventable in many cases. But obesity may not be the biggest risk for the disease. According to an authoritative organization, two major risk factors for breast cancer, which are absolutely certain, are medical radiation used in medical diagnostics and hormone therapy. Some experts claim that preventing vitamin D deficiency may help prevent 75 percent of breast cancer cases."
